XFS has a bug where directory readahead completions can occur after unmount. This can lead to a crash or panic because metadata read verification attempts to access core XFS data structures (e.g., the log) after they have been freed and certain pointers have been reset. Add a test that triggers directory readahead, delays the readahead I/O and immediately unmounts the filesystem. This test is part of the dangerous group as it will cause kernels affected by the bug to crash.
